Application filed March 10, 1913.

Specification of Letters Patent. il' ,iatim't ual Serial No. 753.1536.

To all 'zo/mm '/zt may colare/ra.

Be it llznown that I, Erna H. RYON, a Citizen oit' the United States, residing at 'Valthani, in the County of Middlesex and State ot' litlassaehnsetts, have invented eertain new and useful lmproveinents in Patitern lvleehanisin :t'or Loonis, oit which the :following is a speeilieation.

My invention relates to a pattern mecha nit-im 'for looms, and the object ot' lny inii'ention is to pro vide a pattern mechanism of in'iproved construction, and particularly adapted to be used on loonis ttor weaving' piel; and piel( tor a pref'leterniined time, to roel( the box pattern Chain cylinder bart: and ilorth, through the action oli an oseillatin'gr pin wheel, which nieves two bars ot ,he box pattern Chain into aetion alternately, 'tor the vibrator levers oft the well known `Knowles head motion.

ln my improvements, l provide an oseillating segment gear which meshes with a toothed portion on a pin wheel, and. rause.Vl the piu wneel to be rot-,lied in one direetion :tor one piel( and in the opposite direction :tor the other piek. Said pin wheel operates a star wheel, which is 'tast on a sleeve on the box pattern chain cylinder, which oilierates the vihrator levers in the usual way.

My invention consists in certain novel :Features et construction ol? my improvements as will be hereinafter tully deseribed.

l have shown in the drawings my improvements eoinbined with the well known type ot drop box pattern ehain meehanism, and multiplier pattern el ain nieehanisn'i,op erated by pin wheeis, and star wheels, shown and deseribed in ll. Si. Letters late-nt N o. l-'l ,f-t30, dated October 2Q, 1889.

'm l have only shown in the drawings i detaehed portion ot the drop box pattern eliain ineeliaifrnn, and the multiplier pattern chain mechanism, with my improvements eolnbined therewith, sull'ieient to enable those skilled .in the art to understand the eon-A st uetion and operation thereot.

Referringl to the drawing.: -lfigure l. is a sectional tront view ot' a box pattern Chain meehanisin, and a multiplier pattern ehain meehanisni. with my improvements-i applied thereto, said seetion taken at a point indieated by line Al, l, Fig. Q, looking4 in the direction ot arrow a, same tieni-e. ltigr. 2 is an end View of the parts shown in Fig. l, looking :in the direction of arrow t), saine ligure. Figi. $3 is a sretion, on line il, 5l, lig. l, looltintll in the direction ot arrow t), saine ligure. figr. l eorreslmnds to l `i,e,'. il, but .shows some ot the parts` shown in Fig. tl, in` a dill'erent position, and, llig. i3 is a sertional view ot the pin wheel lnerhanisni, del aol ed.

l'n, the areompanyiun drawings, l isa portion ot a leoni head l unie, on whirh .is seeured a stand L?, on which stand are supported the several parts ot the pattern ehain indieatine nieehanisin. i

il ia a sha tft, suitably sumiorted, which has a sleeve tmounted thereon, earryine' the pattern elian eyninder o, see Fie'. .1, having),` thereon the drop box pattern ehain ti, made up ot linlt's and bars, said bars Carrying,l rolls and tubes, in the ordinary way.

(n the outer end ot the lsha'lt il is loosely mounted the pattern (chain evlinder t, are hin's. l and Ll, rarryingl the auxiliary n|ultiplier pattern chain i), made .lp ol liuto: and bars. said barsea1"r vinj;l rolls and tubes, in the ordinary way. Fast on the sleeve t-i on the multiplier pattern chain` c 'vlint'ler is a` star wheel l0.

.ll.te11tling,r over the hov pattern chain (l is an indirator lever lt, whieh is pivoted on a shatt lg), hij.; i2, on the Atrame l, and eounreted, through the ronueetor llt. and :nele lever ll, piveled at lt? ou a stationary rod lll, willi a eollar t'l1 on a long gitudinally slidingl rod lh, see bien l. The outer lund olE the sliding;- rod .lt-l hasl a volte shaped arm lil :tast thereon, whit-li en; its a pin wheel Qt), splined on a rotary driven ster-,ve zl, having' the gear i thereon. which sleeve is loosely mounted ou a .stationary ,ah-att 12, see itin'. the pin vrhrel i? ie a' apted to be moved into and out el" en with the star wheel lt) ot the rhain eylint'ter tl. thi-inuit: the box pattern ehain t.

il.. sprinp il, see hip". t. serured to an e3;- tension lll on an angle lever llt, and to a stationary part ot the trame, arts` to move the angle lever tt and the rod lh, and earry the pin wheel ltl out ot engagement. with the star wheel lt). llivotallj, mounted on a stand 2l. seeured to the traine is an indieator lever ilo, see ili` i3. wh'uh extends over the multiplier 'pattern rhain tl. and whifh is eonneeted. through a eouneetor lll and an angle lever tl?. pivoted at` E28 on the stationary rod lt, with a eollar 2t) 'ita on a longitudinally sliding rod 30, see Fig. l. rllhc sliding rod has fast thereon the two yolre shaped arms 3l and 3Q, Which are adapted to engage and hold in place on the sleeve 2l the tivo pin Wheels 33 and 34. The pin Wheel 33 is splined on the driven rotary sleeve 2l, see 5, and is adapted to move into and out of engagement with the star Wheel 7 ot the boX pattern chain cylinder 5, seo Fig. l. A spring is attached at one end to an extension 2l on an angle lever 27, and to a stationary part oi the iframe 2, and acts to move the angle lever 27 and the sliding rod 30, and carry the pin Wheel 33 out oit' engagement with the star Wheel 7.

The shaft 3G, see l? l, which is driven from the chain shaft gear, not shown, in the usual Way, on its opposite end, has mounted thereon, the pinion 37, see rig. 2, which meshes with and drives the gear 2l on the revolving sleeve 2l, to operate the pin Wheels 2.0 and '33, which in this instance make a complete revolution every tivo picks. The pin wheels QG and 23 are provided With tivo arms, carrying pins 2G; and Q3, respectively, to operate the star Wheels l() and 7, see VFig. l.

All ci the above mentioned parts, except the pin xvii-el 8e, may be of the usual and Well kno-Wn construction, and operated in the usual and Well l-fnoivn ivay.

.l Will new describe my improvements, which above stated, consist of means for rocking the box pattern chain cylinder bach and iorth for a pr-edetermined time.

The pinion 3? on the shaft 36 also meshes with and drives a gear 3S, see Fig. 2, Which in this instance is loosely mounted on a stud 39 on the frame 2. The gear 38 has a crank pin 4:0 thereon, to which is pivotally connected one end of the connector di; the other end or' the connector el is pivot-ally connected to a stud on. the oscillating gear e3. The oscillating gear in this intance a segment gear, has its hub 43 loosely mounted on the stud on the haine rThe revolving ot lle gear 3% causes the nent ge r il, 'through the connector ll, to `.-.cnlate the pin whe-el Sel, which in this instance is loosely mounted on the sleeve 2l, and has the toothed portion 34', see Fig; 5, the een, which meshes with the teeth on the n. nent gear e3, which causes the pin Wheel 34: to be rocked, in one direction for one piclr, and in the opposite direction for the other piclr, see llig. el. lilhen there is no roll on the multiplier pattern chain 9 under the indicator l-ver 25., the pin Wheels and are caused to slide to the left in l, through the action of the spring o, and the oscillating' pin Wheel 3ft is ioved into engagement With the star Wheel which is fast on the sleeve a of the boit l pattern chain cylinder 5. The pin Wheel` causesV the pattern chain cylinder to v roel; back and forth, and-bring tWo contiguous bars of the box pattern chain 6 intoV action alternately, under the vibrator levers, not shown. lWhen a roll of the multiplier pattern chain 9 moves under the lever 25, 70V the pin Wheels 33 and 34 are caused to slide to the right in Fig. l, and the pin Wheel 33 is mov-ed vinto engagement with the star wheel 7, and the box pattern chain 6 is" caused to move forward every pick in the 7 5 same direction, as long as a roll on the multiplier pattern chain 9 is under the lever 25.

lnstead of hz'iving a double pin Wheel 20, which operates the multiplier pattern chain cylinder 8 every pick, a single pin Wheel 8.0V may be employed, Which Vin this instanceY will advance the multiplier pattern chain 9 one bar for every two picks, and tivo difierent kinds of filling may be interwoven by each bar of the multiplier pat-tern chain.

lt Will be understood that the details of construction of my improvements may be varied if desired.

Having thus described my invention, what lf claim as new and desire to secure by Letters Patent is:

l. ln a pattern mechanism for looms, pattern surfaces, a star Wheel connected therewith, tivo pin Wheels to operate said Star Wheel, means to rotate one of said pin Wheels continuously in one direction, and means toY oscillate the other pin Wheel, and means to move either of said pin Wheels, to operate said star Wheel.

2. ln a pattern mechanism for looms, pattern surfaces, a star Wheel connected therewith, two pin Wheels to operate Said star Wheel, means to rotate one of said pin Wheels continuously in one direct-ion, and'means to oscillate the other pin Wheel, said oscillatmeans including teeth on the last mentioned pin Wheel, said teeth meshing` with and driven by an oscillating gear, and said oscillating gear.

3. ln a pattern mechanism for looms, pattern surfaces, a star wheel connected therewith, tivo pin Wheels to operate said star Wheel, means to operate one of said pin Wheels continuously in one direction, and means to oscillate the other pin Wheel, said means including a driven gear, a crank hereon, a connector to a Vsecond gear, to oscillate said second gear, and said second gear, meshing With and driving said oscillatins,` pin Wheel, and means to move either of said pin Wheels, to operate said star Wheel.
